One of the least expensive and reliable technologies available is eInk. It is most commonly used in things like eReaders, calculators, and watches. At CES 2014 we saw a few of the newest ways it is poking into everyday lives. I was able to try out the new eInk luggage tag. With this luggage tag there will be no more waiting in line to check bags. The eInk luggage tag uses RFID to transfer flight information from your smartphone or tablet to the reusable luggage tag via Bluetooth. Simply input your flight information and sync to the tag. In addition to flight numbers, the eInk tag will also display a barcode for the airline to scan.
Another really cool feature of the luggage tag is that you can track your luggage location. Periodically the tag will send a text message to your phone. This should lead to less lost luggage.
These tags are currently being tested by British Airways. Availability and price have not yet been announced.
